New approaches to multiciterial evaluation of alternatives in decision-making

This work is devoted to the development of mathematical models that make it possible generalize data obtained in multicriteria assessment alternatives when making decisions under certainty conditions. A typical problem multi-criteria integration particular criteria-based assessments into some integral indicator reflecting degree attractiveness alternatives. Traditionally, for these purposes, an additive method was used, which consists fact final alternative sum by criteria, possibly multiplied weights criteria. However, this approach has a number significant disadvantages, include following. When evaluating alternatives, such their validity as feasibility not taken account, leads distortion result due too simple or difficult Evaluations qualitative and attributive criteria are subjective, since they expert methods, introduces subjectivity alternative. The depends on composition assessed set To eliminate second drawback, model proposed, implies introduction certain numerical criterion, each have different meaning, while value. relation considered fuzzy, with belonging function depending indicator.
